Some of you guys are too emotionally involved in this, bickering back and forth. It's embarrassing.
There is NO pattern. And NO, a lack of a pattern is not in itself, a pattern. Either solve it deterministically or randomly by pure astronomical luck.
Someone WILL solve #72 and it won't be because of some hidden pattern or some hidden message the creator said (or didn't say) in his two forum posts.
Just divide into subranges, rent GPU's and iterate. Can't afford it? Then go full random.
Friend, I understand you may not have your own opinion because
you repeat and cite others. But let me tell you something you
might not have thought about. Maybe then you will start thinking
differently about this puzzle. Maybe you will finally understand
that one should think independently and interpret everything,
not just duplicate.
I have read a lot of posts on this thread, I don't even remember
all of them anymore. But let me ask you one simple question.
Did any of you ever think about it this way:
You all analyzed amounts, dates, other data. But did any of you
think that the amounts (from 0.001 to 0.256 BTC) were simply a
technical part of the transaction? This is a transaction, so the
creator HAD to add some amounts to make it go through at all.
He just matched them to the puzzle ID and the bit count. In my
opinion this is a simple by-product, nothing more meaningful
in itself.
Something everyone looked at, but no one thought about it
differently. And that's exactly what's interesting. On this
thread I see three groups of people:
1. Those who promote and sell apps, those who profit from brute
force.
2. Those who analyze all the data piece by piece (I belonged
here once myself, after I got bored of brute).
3. Those who started analyzing the PURPOSE of the puzzle. I am
here now.
And one more thing before I move on. I have a lot of further
observations and they will come out over time. What is really
fun is that this is becoming like a detective game. I'm counting
on the creator finally speaking up. Not with a hint, but with a
confirmation of the direction of thinking.
One last question for the brute force crew. Did any of you ever
think that at the time this puzzle was being created, the reward
was so small that brute forcing it was not even profitable at
all? It was better to use that GPU energy on regular mining. So
what was the PURPOSE of creating such a puzzle?
I leave you with that to chew on. It's a bit like looking at the
same picture in two different ways. Some only see the surface,
others see what is underneath. Stay with your apps. Yes, your
apps are great.
